jQuery学习笔记之总体架构

复制代码 代码如下:

(function (window, undefined) {
            //构建jQuery对象
            var document = window.document,
                navigator = window.navigator,
                location = window.location;
            var jQuery = (function () {
                var jQuery = function (selector, context) {
                    return new jQuery.fn.init(selector, context, rootjQuery);
                },
                _jQuery = window.jQuery;
                //............................
                //............................                 
                return jQuery; //981行
            })();
            //工具方法:Utilities;我在jQuery源码中没有发现是哪一块,如果有发现的.可以告诉我一下
            //回调函数列表 Callbacks
            //异步队列 Deferred
            //浏览器功能测试 Support
            //数据缓存  Cache
            //属性操作  Attributes

            //坐标 Offset. 尺寸Dimensions
            window.jQuery = window.$ = jQuery;
        })(window);
